How to make a selection from the database if the column is named KEY?

Question

MySQL

Oru Chot.
Opencart has a setting table that stores store parameters. Each parameter is assigned a key.
The problem is that the key column is named with the reserved word KEY and I can't make a fetch using PDO because the query fails. What can be done in this situation?

$stmt = $this->dbh->prepare("SELECT * FROM z_setting WHERE key=:key");
    $stmt->bindParam(':key', $key, PDO::PARAM_STR);  
    $stmt->execute();
    return $stmt->fetchAll();

Answer 1

$stmt = $this->dbh->prepare("SELECT * FROM z_setting WHERE `key`=:key");
